  In the conventional air cleaner with a humidification function, the air purification unit, the fan, and the tank are arranged in this order from the front side of the main body. For this reason, when viewed from the front of the main unit, the tank is hidden by the cleaning unit and fan, so it is difficult to check the amount of water in the tank from the front side, and the tank is located on the back side of the main unit. There is a problem that considerable labor is required for work such as storage and storage. In addition, there are many cases where the air purifier with a humidifying function is arranged as close as possible to the wall on the back side of the air purifier because of the user's request to secure as much free space in the room as possible. Therefore, on the back side of the main unit where there is little user intervention, the noise is blocked by the tank and walls, but the front side of the main unit close to the user's living space has nothing to block the noise. Is transmitted to the user who is in front of the main body without being shielded, and the user has a problem of being uncomfortable and uncomfortable.

  The present invention has been made to solve the above-described problems, and a first object of the present invention is to provide an air cleaner with a humidifying function that allows a user in front of the main body to be hardly aware of noise. And It is a second object of the present invention to provide an air cleaner with a humidifying function that allows a user to easily check the amount of water in the tank visually.

  An air cleaner with a humidifying function according to the present invention includes a main body casing, a tank having a water meter indicating the amount of water on the front surface, a water tray provided at a lower portion of the tank and receiving water dripping from the tank, and a rear surface of the main body casing. An air purification filter that is provided on the side and sucks and cleans air from the back surface, a vaporization filter that sucks and absorbs water from the water tray and vaporizes the air purified by the air purification filter, and water vapor generated by the vaporization filter. And a fan that sucks clean air that is contained and forcibly discharges it to an external space such as a room, and a tank is provided on the front side of the main casing.

  According to the present invention, since the tank is arranged on the front side of the main body casing of the air cleaner with a humidifying function, the noise generated from the main body is shielded by the tank and the water in the tank. The user in front of the cleaner is hardly aware of the noise generated from the air cleaner with a humidifying function. Further, the user can easily confirm the amount of water in the tank visually.

FIG. 6 is a side cross-sectional view of the air cleaner with a humidifying function as viewed from the lateral direction, and also shows the air moving direction. FIG. 7 is a side sectional view showing the case where the tank is removed in FIG.

Next, the structure of the air cleaner with a humidification function in Embodiment 1 of this invention is demonstrated using FIGS.
The air cleaner with a humidifying function is provided on the front side of the main casing 1, on the back side of the door 2, on the tank 3 with a water meter 301 on the front side, and on the lower part of the tank 3. A water receiving tray 4, a filter cover 5 provided detachably on the back side of the main casing 1, a deodorizing filter 6 provided on the front side of the filter cover 5, and a front side of the deodorizing filter 6. An air purifying filter 7 for collecting fine dust floating on the air, an intake / exhaust sirocco fan 9 provided on the front side of the air purifying filter 7 and driven by a fan motor 8, and a lower part of the sirocco fan 9 An air channel partition that is provided on the front side of the air purification filter 7 and that is in contact with the rear surface of the tank 3 and forms an air channel 11 between the front side of the vaporization filter 10. A plate 12, and a power supply board 13 and the operation panel 14. for operation control of the fan motor 8. An operation unit 141 is provided on the operation board 14. One surface of the air passage partition plate 12 is in contact with the rear surface of the tank 3, and the air passage partition plate 12 extends to a position where at least the other surface faces the sirocco fan 9. A handle 15 is attached to the door 2, and a handle 16 is attached to the tank 3. Further, as shown in FIG. 3, the left side of the door 2 is pivotally supported by the support portions 17 and 171, and the user puts his / her hand on the handle 15 attached to the right side of the door 2 and pulls it forward. The right side is configured to rotate about the support parts 17 and 171 and open to the front. In addition, you may form the window which confirms the water meter 301 of the tank 3 in a door. In this case, the window may be a simple opening, or a transparent plate may be attached to the window. As a result, the user can check the amount of water in the tank 3 at any time without opening the door 2. Moreover, as shown in FIG. 4, air is sucked from the suction portion 18 on the back surface of the main body, and air is discharged from the air discharge port 19 on the upper portion of the main body. Further, the sirocco fan 9 and the vaporization filter 10 are arranged on a straight line. Thereby, since the air path 11 is also formed on a straight line, it becomes possible to reduce the air path resistance of an exhaust flow.

  As shown in FIG. 5, the vaporization filter 11 includes a filter material that easily absorbs water by capillary action, and a frame that houses and fixes the filter material. During operation, air passes horizontally through the vaporization filter 10 from the back, and the air that has passed through the vaporization filter 10 rises up the air passage 11 constituted by the vaporization filter 10 and the air passage partition plate 121 and is located above. Sucked into fan 9. The air passage partition plate 121 may be extended upward to serve also as the air passage partition plate 12.

Next, functions of the first embodiment will be described. In order to remove the tank 3 from the water tray 4 for water supply, first the handle 15 of the door 2 is put on the hand and the pulling door 2 is opened to the front. Next, the user holds the handle 16 of the tank 3 and pulls the tank 3 forward while lifting the tank 3 upward. As a result, the protruding portion 20 that has penetrated into the hole in the lower portion of the tank 3 is removed, and the tank 3 can be taken out. FIG. 7 shows a state after the tank 3 is taken out.
Further, when the tank 3 which has been supplied with water is stored again, after opening the door 2 in the same manner as described above, the tank 3 is pushed backward while holding the handle 16 of the tank 3 and the lower part of the tank 3 is pressed. Is dropped in accordance with the recess of the water tray 4. As a result, the protrusion 20 of the water tray 4 penetrates into the hole at the bottom of the tank 3, and the water in the tank 2 drops onto the water tray 4.

As shown in FIGS. 5 and 6, the air is sucked in from the back side of the main body (at least one of the back side and the both side ends of the back side) in the direction indicated by the thick white arrow by the suction force of the sirocco fan 9, and the deodorizing filter 6 Is deodorized and cleaned by the air purification filter 7. By including not only the back side but also both side ends on the back side in this way, the suction effective area is increased, so that the suction efficiency can be increased.
The deodorized and purified air passing through the upper part of the air purification filter 7 is directly guided to the sirocco fan 9.

  Further, the deodorized and purified air passing through the lower part of the air purification filter 7 passes through the vaporization filter 10. At this time, the water sucked from the water tray 4 by the vaporization filter 10 is vaporized by the deodorized and purified air, and is guided to the sirocco fan 9 through the air passage 11. The sirocco fan 9 is driven by a fan motor 8, and dried clean air and humidified clean air are discharged from an air discharge port 19 in the upper part of the main body and supplied to a room.

  Further, since the noise generated from the sirocco fan 9 and the main casing 1 is shielded by the air passage partition plate 12, it can be considerably attenuated. Further, the tank 3 and the door 2 are disposed in front of the air passage partition plate 12, and when the door is closed, noise can be considerably attenuated by the double shielding effect. In particular, since water is stored in the tank 3 and is considerably absorbed by the water, the user on the front side hardly needs to be aware of noise.

  In addition, in order to cool the power supply board 13 which is one of the heat generation sources, a part of the air that has passed through the air passage 11 reaches the power supply board 13 installed above the air passage 11 and this power supply board. The heat generated from 13 is cooled. The air heat-exchanged by the power supply board 13 is sucked in by the sirocco fan 9, is discharged upward from the upper air discharge port 19, and is supplied indoors.

  According to the first embodiment, the tank is arranged on the front side of the main body casing of the air cleaner with a humidifying function, and the noise generated from the main body is shielded by the noise partition plate. The user who is in front of is effective in being almost unaware of the noise generated from the air cleaner with a humidifying function. Moreover, there exists an effect that the user who exists in front of the air cleaner with a humidification function can confirm the water quantity of a tank easily visually.

Embodiment 2. FIG.
1-4 are also used in the second embodiment. FIG. 8 is a diagram showing a configuration of an air cleaner with a humidifying function according to Embodiment 3 of the present invention, and since the configuration is the same as that of FIG. In the second embodiment, the air passage partition plate 122 obtained by cutting a part of the air passage partition plate 12 used in the first embodiment is used, and the cut portion of the air passage partition plate 12 is used as the rear portion of the tank 3. Is supplemented by In other words, the air passage 11 is constituted by the front side of the vaporization filter 10, the back side of the tank 3 and the back side of the air passage partition plate 122, and is configured to communicate with the sirocco fan 9. FIG. 9 is a side sectional view showing the case where the tank is removed in FIG.

Next, the function of this Embodiment 2 is demonstrated using FIGS. 1-4 and FIGS. 8-9. Since the function of each component and the air flow are the same as those of the first embodiment, only different points will be described. When taking out with the tank 3, it carries out similarly to Embodiment 1. FIG. FIG. 9 shows a state after the tank 3 is taken out. The air humidified and cleaned by the vaporization filter 4 passes through the air passage 11 and is guided to the sirocco fan 9. Subsequent operations are the same as those in the first embodiment.
Further, noise generated from the sirocco fan 9 and the main body casing 1 can be considerably attenuated by the air passage partition plate 121 and the tank 3. In particular, since water is stored in the tank 3 and is considerably absorbed by the water, the user on the front side hardly needs to be aware of noise. Further, when the door is closed at the portion without the tank, the noise attenuation can be considerably increased by the double shielding effect of the air passage partition plate and the door.

  According to the second embodiment, the tank is arranged on the front side of the main body casing of the air cleaner with a humidifying function, and the air passes through the rear side of the tank. Since it is shielded and considerably attenuated by the water in the back surface and the tank, there is an effect that the user on the front side of the air cleaner with a humidifying function does not need to be aware of the noise generated from the air purifier body with the humidifying function. Moreover, there exists an effect that the user who exists in front of the air cleaner with a humidification function can confirm the water quantity of a tank easily visually.

Embodiment 3 FIG.
1 to 4 are also used in the third embodiment. FIG. 10 is a diagram showing the configuration of the air cleaner with a humidifying function according to the third embodiment of the present invention, and is the same as FIG. 8 except that a noise shielding plate 21 is added, so only the differences will be described. As shown in FIG. 10, in the third embodiment, a noise shielding plate 21 is provided that connects the upper back of the tank 3 and the upper part of the sirocco fan 9 facing the tank 3 and spreads across both side surfaces of the main body. Therefore, all the noise that reaches the front from the sirocco fan 9 is guided to the tank 3 containing water. Since the tank 3 is filled with water and the noise absorption efficiency of the water is higher than that of the air passage partition plate 121 of FIG. 8, the noise absorption efficiency is higher than in the first and second embodiments. Therefore, there is an effect that the user who is in front of the air cleaner with a humidifying function does not need to be further aware of the noise generated from the air cleaner with the humidifying function. Moreover, there exists an effect that the user who exists in front of the air cleaner with a humidification function can confirm the water quantity of a tank easily visually.

Embodiment 4 FIG.
1-4 are also used in the fourth embodiment. FIG. 11 is a diagram showing a configuration of an air cleaner with a humidifying function according to Embodiment 4 of the present invention. Here, only different parts in the configuration will be described. The lower part of the tank 31 forms a hemispherical convex part, and the tank contact part 411 of the water receiving tray 41 forms a hemispherical concave part so as to be fitted to the hemispherical lower part of the tank. Further, the lower hole of the tank 31 that is penetrated by the protrusion 20 has a larger hole than the protrusion 20 so that the protrusion 20 can be easily removed from the lower hole of the tank 3 when the water tray 4 is pulled out. . The vaporization filter 101 is shorter than the first to third embodiments, and the lower part forms a hemispherical convex part, and the vaporization filter contact part 412 of the water receiving tray 41 is fitted to the hemispherical lower part of the vaporization filter 101. Thus, a hemispherical recess is formed.
The vaporization filter 41 is detachably fixed to the upper body casing 22.
Further, the lower portion of the tank 31 is configured to be a little thin, and the tip of a stopper 23 fixed to the main body casing 22 is protruded in the vicinity of the slender portion of the tank 31, and the tank 31 is lowered. In this case, the tank 31 is configured so that the tank 31 does not lower any more when the tip of the stopper 23 comes into contact with the thick portion of the tank 31 and stops.

  Next, functions of the fourth embodiment will be described with reference to FIG. When the water tray 41 is pulled out, the tank 3 is not removed and the handle of the water tray 41 is held and pulled out a little more strongly than in the first to third embodiments. Thereby, the hemispherical convex part of the tank 31 lower part is gradually pushed up by the tank contact part 411 of the water receiving tray 41, and the projection part 20 which penetrated into the hole of the tank lower part remove | deviates from a hole. At the same time, since the vaporization filter 101 is made of an elastic material, the hemispherical convex part at the lower part of the vaporization filter 101 is gradually pushed up by the vaporization filter abutting part 412 of the water receiving tray 41, and the elastic member is distorted. 101 is detached from the water tray 41 while being fixed to the upper main body casing 22. Thereby, the water tray 41 can be pulled out forward. In addition, after the tank 31 is lifted on one end by the water receiving tray 41, the tank 31 is naturally lowered by gravity and stops at the position of the stopper 23. Further, the lower part of the vaporization filter 101 is also lifted up by one end by the water tray 41 and then naturally falls by gravity. However, since the vaporization filter 101 is fixed to the upper body casing 22, it is suspended. The vaporization filter 101 is detachably attached by screws, nails, clamping, or the like. For example, in the case of sandwiching, the upper frame body of the vaporization filter 101 is attached in a state of being sandwiched between the guides by being pushed into the back in accordance with rail-shaped guides that are provided on both sides of the main casing 22 and become narrower toward the back. When cleaning the vaporization filter 101, the vaporization filter 101 can be easily removed by taking out the tank 31, putting a hand behind the vaporization filter 101 and applying a little force to pull the vaporization filter 101 forward. It can be taken out. When attaching, the reverse procedure is sufficient.

  According to the fourth embodiment, in addition to the effects of the first and second embodiments, when the water tray is taken out or stored, the tank does not have to be removed one by one. In addition, the work load is reduced.

Embodiment 5. FIG.
1-4 and 8 are also used in the fifth embodiment. When the room is hot, cold water is previously added to the tank 3 of the air purifier with a humidifying function, so that the air that has passed through the vaporization filter 10 passes through the air passage 11, and the cold water of the tank is placed behind the tank 3. It is cooled by heat exchange. As a result, the cooled air is sucked into the sirocco fan 9 and is discharged upward from the air discharge port 19 in the upper part of the main body and supplied into the room. As a result, the room can be cooled with the humidified purified air, and the comfort level of the user can be improved.
On the contrary, when the room is cold, hot water is previously added to the tank 3 of the air purifier with a humidifying function, so that the air that has passed through the vaporization filter 10 passes through the air passage 11, Heated by heat exchange with hot water in the tank. As a result, the warmed air is sucked into the sirocco fan 9 and is discharged upward from the air discharge port 19 in the upper part of the main body and supplied into the room. Thereby, indoor heating becomes possible with the humidified purified air, and a user's comfort level can be improved.
In the above example, the air in the air passage is in direct contact with the tank, but the air in the air passage and the water in the tank 3 exchange heat through the air passage partition plate 12 as shown in FIG. May be. In this case, the air path partition plate 12 may be slightly inclined so that the air path gradually becomes wider as it goes downward. As a result, when the tank 3 is stored while being pushed inward, the rear surface of the tank 3 and the air path partition plate come into closer contact. Thereby, in heat conduction from the tank 3 to the air path partition plate 12, waste is reduced, and heat exchange efficiency between cold water or hot water and air is improved. In this case, an extra space is provided between the tank 3 and the door so that there is no problem even if the tank is slightly inclined.
Moreover, you may add a fin to the surface at the side of the air path of the air path partition plate 12, as shown in FIG. Heat exchange efficiency is improved by adding fins.

  In the above example, the sirocco fan has been described as an example, but it is needless to say that the present invention is not limited to this. For example, a propeller fan may be used.
